One of my fluorecent green mushroom (disc anemone) moves away from its own LR (there are lots of them on the LR, but only this moves) and drop on the sand. It grows there and seems to love it, but why did they moves? My water specs are alright. And light level is also adequate. But there is medium to strong current at the LR where it used to be (where all the mushrooms were), is the current forcing the mushrooms to move? BTW there is also little NO3, could that be the case?
